ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

The nose can be an efficient filter for inhaled gases, vapours and particles that may be harmful to the lung. Nasal airways may also be targets for injury caused by inhaled toxicants. To investigate the nasal toxicity of carbon black nanoparticles (CB), rats were exposed to 0, 1, 7 or 50 mg/m? of high surface area CB (HSCB; primary particle size 17 nm; particle surface area 300 m?/g) for 6 h/day, ...

Geomembrane installations often cover substantial areas. Landfill cells pose enormous footprints. Oil and gas pits, industrial processing ponds, and wastewater containment ponds are large installations too, and each year they tend to be built a little larger. The scaling up of these facilities is not just a matter of achieving better operational economics for the ...

As many countries fail to meet air quality targets and large numbers of premature deaths still result from air pollution, Jim Mills, a particulate monitoring specialist and Managing Director of Air Monitors, explains why 2013 will be a pivotal year. In November 2011 Janez Potočnik, European Commissioner for the Environment, expressed his determination to make 2013 the ‘Year of ...

In recent years, a consensus has emerged that exposure to traffic emissions increases risks of adverse health effects for populations living, working, or going to school near large roadways.1-4 Near-roadway air pollution is characterized by elevated levels of trafficgenerated compounds compared to overall urban background levels with the gradual decrease in concentrations within several hundred ...

Analox is breaking into new markets after the first Ax60 carbon dioxide detector was installed in McDonalds in China. Analox have a global agreement with McDonalds to distribute Ax60’s to their restaurants all over the world, and the very first unit ...

Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

Environmental chemicals are wreaking havoc to last a lifetime The numbers are startling. According to the U.S. Centers for Disease Control and Prevention, about 1.8 million more children in the U.S. were diagnosed with developmental disabilities between 2006 and 2008 than a decade earlier. During this time, the prevalence of autism climbed nearly 300 percent, while that of ...

Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been in use for decades and during that time a number of studies have been conducted to test its longevity and ability to meet environmental sustainability project requirements. Here, we explore some of those studies to examine the benefits of HDPE ...

Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

The Acta Group's (Acta) thoughts are below on what may be headed our way in 2013 from the U.S. Environmental Protection Agency's (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP). Although the 2012 Presidential Election is over, environmental issues will continue to be used to make distinctions between the two parties (or between the House and Senate). Speculation is currently rife ...

Bergeson & Campbell, P.C.'s (B&C) thoughts are below on what may be headed our way in 2013 from the U.S. Environmental Protection Agency's (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP). Although the 2012 Presidential Election is over, environmental issues will continue to be used to make distinctions between the two parties (or between the House and Senate). Speculation ...

Introduction Many of us who work on environmental issues have faced the challenge of conveying their importance to nonspecialists. Perhaps we have found ourselves defending the robustness of climate science to a contrarian uncle, or extolling the importance of biodiversity to a dubious aunt. Our relations and friends are often educated people, skilled in their own professions, who have ...
